Well, not really. Because: A greet is not a guided city tour. A greet is a personal encounter with a local, i.e. a person living in the city you are visiting. That person will show you Innsbruck from his or her very personal perspective. She will tell you stories from daily life in Innsbruck, anecdotes of past and present and some facts about the city, too.
In case you prefer a classical guided tour, here are some links to professional services:
Austria Guides – all pros at once
Tourism-Board Innsbruck, Guided City Tours
